It's no use. Learn the hard way.
OK, superchargers have been used on cars since the days of Packard and Duesenberg. Turbo's have been in use for at least as long
Again, not new.
VVT? Well, common implementations started in the 90's. So it isn't new now either.
DI? Mercedes was using DI in the 50's IIRC.
So none of these technologies are new by themselves. The least common of the bunch is DI, the others have been used (successfully) in the past few decades, some in combination with each other (IE, forced induction in combination with VVT), with no real issues to report.
It is the DI implementations on top of these things that have raised a few questions about things like fuel dilution. But these issues also seem to vary wildly by manufacturer.
Ultimately, implementations like Ford's have been on the scene for a while now with nothing much to report other than a few growing pains (like the intercooler bug). Given the track record of forced induction DI diesels, as long as the engine is built properly (which it seems to be), then they really aren't the gamble you seem to think they are.
